Kevin Jairaj/USA TODAY SportsOklahoma defensive coordinator Mike Stoops is one of the highest-paid assistant coaches in the Big 12.

Texas defensive coordinator Manny Diaz, who was fired after the Longhorns' loss at BYU the second game of the season, tied for highest pay in the league for 2013 with an annual salary of $650,000. Texas offensive coordinator Major Applewhite and Oklahoma defensive coordinator Mike Stoops both made the same amount to top the Big 12.

Diaz, Applewhite and Stoops were the only three Big 12 assistants to rank in the top 25 nationally in pay.
